When using the webcam in your flash applications, it can be handy to flip the video object so it acts like a mirror. Many of the flash webcam demos out there does exactly this, usually by setting the scaleX property of the video object to -1. Unfortunately, because the registration point of the video object [...]
With the introduction of FLARToolkit and other means of tracking user input through a webcam in flash, I recently had a chance to read up on some of the other ways we can interact with flash applications using a webcam. Camera.activityLevel The most basic way to detect activity through a webcam in flash is by [...]
Now that we’re knee deep in iPhone game development, we’re working with a number of different outside developers. Since everyone involved is pretty new to Objective-C, XCode and iPhone development, project organization and coding conventions in our projects have been all over the map. To improve the quality of our projects and make them easier [...]
Using Box2D is a great way to add physics to a 2D iPhone game. Since Box2D is written in C++ rather than Objective-C, adding it to your XCode project and getting it to build cleanly can be a bit tricky. If you just want to get aquainted with Box2D, there is an sample XCode project [...]
When developing iPhone games, one of the biggest performance optimizations you can make is to use OpenGL ES for rendering (instead of CoreGraphics or UIKit). For a 2D game like Arctic Shuffle, this means loading all of the animation into Open GL as textures, and drawing them onto simple rectangular shapes. There are two caveats [...]
